I was in a shop the other day and saw what looks to be a good swap in progress. It was a 318 V8 out of a GC going into a TJ. The wiring harness was almost a perfect match. There were only two (maybe 3) connections that needed modification. The TJ just needed a 1" BL to get all the components to line up right on.
